In this operation mode, autonegotiation can be performed, as described in IEEE802.3. The DP83869 has a set of fiber-specific registers located at offset 0xc00. When the transceiver is configured in RGMII-to-1000base-x mode, these registers are mapped onto offset 0, which should make reading the autonegotiation status transparent. However, the fiber registers at offset 0xc04 and 0xc05 follow the bit layout specified in Clause 37, and genphy_read_status() assumes a Clause 22 layout. Thus, genphy_read_status() doesn't properly read the capabilities advertised by the link partner, resulting in incorrect link parameters. Similarly, genphy_config_aneg() doesn't properly write advertised capabilities. Fix the 1000base-x autonegotiation procedure by replacing genphy_read_status() and genphy_config_aneg() with their Clause 37 equivalents.

In this operation mode, autonegotiation can be performed, as described in IEEE802.3. The DP83869 has a set of fiber-specific registers located at offset 0xc00. When the transceiver is configured in RGMII-to-1000base-x mode, these registers are mapped onto offset 0, which should make reading the autonegotiation status transparent. However, the fiber registers at offset 0xc04 and 0xc05 follow the bit layout specified in Clause 37, and genphy_read_status() assumes a Clause 22 layout. Thus, genphy_read_status() doesn't properly read the capabilities advertised by the link partner, resulting in incorrect link parameters. Similarly, genphy_config_aneg() doesn't properly write advertised capabilities. Fix the 1000base-x autonegotiation procedure by replacing genphy_read_status() and genphy_config_aneg() with their Clause 37 equivalents.

The stripes are all in conf->handle_list and new threads can't handle them. Commit b39f35ebe86d ("md: don't quiesce in mddev_suspend()") removes pers->quiesce from mddev_suspend/resume. Before this patch, mddev_suspend needs to wait for all ios including sync io to finish. Now it's used to only wait normal io. Fix this by calling raid5_quiesce from raid5_store_group_thread_cnt directly to wait all sync requests to finish before changing the group cnt.
